fix: dates sent as ISO not DD-MM-YYYY

[mamico]

dates should be sent in ISO format (the widget's default should be fine), not DD-MM-YYYY

@mamico This needs collective.volto.formsupport >= 3.1.4 (specifically collective/collective.volto.formsupport#34) to work right? What happens if the backend is less than this version?

In this case, I believe dates would be saved/sent in ISO format instead of DD/MM/YYYY format.

@mamico This is a breaking change then, right? Otherwise, LGTM!

Not sure if we can call it breaking, but we can document the backend requirement in the README, as we've done for the others.
